Abstract

A disclosed block based data compression system employs two parallel, independent compression networks. One network (20, 22) provides fixed compression, the other network (14, 16) provides variable compression. Compressed data from one or the other of these networks is chosen to obtain satisfactory image quality and a desired compression factor. The output of the fixed compression network is selected for use (25) if a bit counter (18) determines that the output of the variable compression network does not achieve the desired compression factor.
